Starvation response in animals (including humans) is a set of adaptive biochemical and physiological changes, triggered by lack of food or extreme weight loss, in which the body seeks to conserve energy by reducing metabolic rate and/or non-resting energy expenditure to prolong survival and preserve body fat and lean mass.
By doing so, the body can regulate its resources and energy storage efficiently. Another key component of allostasis is the brain's perception and subsequent adaptation to chronic stress. Sterling and Eyer theorized that the brain can anticipate stressors to prepare the body to respond adequately to environmental demands through classical ...
Urinary water loss, when the body water homeostat is intact, is a compensatory water loss, correcting any water excess in the body. However, since the kidneys cannot generate water, the thirst reflex is the all-important second effector mechanism of the body water homeostat, correcting any water deficit in the body.
The English meditation is derived from Old French meditacioun, in turn from Latin meditatio from a verb meditari, meaning "to think, contemplate, devise, ponder". [11] [12] In the Catholic tradition, the use of the term meditatio as part of a formal, stepwise process of meditation goes back to at least the 12th-century monk Guigo II, [12] [13] before which the Greek word theoria was used for ...
Mens sana in corpore sano (Classical Latin: [mẽːs ˈsaːna ɪŋ ˈkɔrpɔrɛ ˈsaːnoː]) is a Latin phrase, usually translated as "a healthy mind in a healthy body". The phrase is widely used in sporting and educational contexts to express that physical exercise is an important or essential part of mental and psychological well-being.
“Sacrificing sleep in order to make time for exercise is a plausible solution that can help improve health and fitness, but it needs to be carefully balanced with managing proper sleep and ...
The two main fuel sources for aerobic exercise in the body include fat (in the form of adipose tissue) and glycogen. At lower intensity aerobic exercise, the body preferentially uses fat as its main fuel source for cellular respiration , however as intensity increases the body preferentially uses glycogen stored in the muscles and liver or ...
Human physiology is the study of how the human body's systems and functions work together to maintain a stable internal environment. It includes the study of the nervous, endocrine, cardiovascular, respiratory, digestive, and urinary systems, as well as cellular and exercise physiology.
